Node in particle model oriented multi-layer direct connection cluster parallel computation system

Abstract

The invention relates to the field of high-performance computer numerical simulation technologies and discloses a design project facing the nodes in a multi-layer directly-connected cluster parallel computing system, which consists of a plurality of logic circuit units having independent operation, storage and communication functions. The logic circuit unit at least has a logic circuit unit being a communication unit capable of directly communicating with other nodes. The other logic circuit units are computing units that execute computation task. Every computing unit is at least in direct communication with the communication unit. The units are different in function and the combination thereof makes the constitution of the node more abundant, flexible and more reliable between nodes and can improve the computing efficiency of node such that the multilayer directly-connected cluster parallel system can much more effectively execute particle simulation.

Description

technical field [0001] The invention relates to the technical field of high-performance computer numerical simulation, in particular to the design of nodes in a particle model-oriented multi-layer directly connected cluster parallel computing system. Background technique [0002] At present, the mainstream way to achieve high-performance computing is massively parallel processing (MPP). Since such a system costs a lot, how to make full use of its hardware resources is an important consideration in the design of MPP. The traditional way of thinking is to make the system adapt to many different algorithms and application problems, that is, to rely on versatility to ensure the fullness of business volume and make full use of system resources. [0003] For this reason, global fast data exchange should be realized in principle, including direct or indirect data exchange between processors and memories and between processors. Under such a design idea, when the number of processor...

AI Technical Summary

Problems solved by technology

At present, even for single-processor microcomputers, the widening speed gap between the data processing speed of the processor and the data access speed of the memory makes it only about 10% of the peak value of the actual efficiency of running many calculation programs. For MPP systems, it is often reduced to only 1-2%

On the other hand, although there are some special-purpose parallel computers for specific algorithms and problems, they cannot be mass-produced and fully utilized because of their narrow application and small business volume, and the economy is very poor, so they have not been focused on development.
